Hell,
I see on the sample http://cesiumjs.org/Cesium/Apps/Sandcastle/index.html?src=Wall%20Outline.html&label=Geometries that the property for line width is a lineWidth for the whole appearance, not matching the polyline width per geometry element…
Btw, changing the line width doesn’t seem to do anything at all. Is it a bug?
I guess i can also use polyline and draw my wall manually…
